let's say you have an image of gray bands of varying intensity.
such as the one seen on the website,
http://encyclopedia.thefreedictionary.com/SDS-PAGE
Is there anyway to change the picture or do something and be able to
get numerical values for those bands?
maybe define a vertical line and then go to the center of the each
bands and measure how intense the gray is.
or maybe define a rectangle and get the gray intensity in that...
is there a packages or codes for doing that? NIH image program which
is freely avaialble can do this. But I wanted to do it in Mathematica.
Thanks for any and all insights.
